WATEX vertical turbine fire pump, UL listed according to the manufacturer’s certificate.
It draws water from underground tanks or a static source, can start with negative suction pressure, and delivers water at higher pressure to sprinkler risers and hose standpipes. It is driven by an electric motor or diesel engine through a gearbox, with an open, water-lubricated line shaft for easy maintenance.
Approval (per the manufacturer):
• UL: UL certificate EX27224 for vertical turbine fire pumps, covering models 100LB, 150LB and 150WV.
• The catalogue lists further models in the range (100 LB-50, 150 LB-32.5, 150 LB-50, 150 WV-32.5, 150 WV-50, 200 WV-60, 200 WVX-60, 250 WV-60); the approval of each model is confirmed on its datasheet with the quotation.
General specifications (per the manufacturer’s catalogue):
• Rated flow: 50 to 1250 gpm.
• Maximum working pressure: up to 420 psi.
• Speed: 1480 to 3190 rpm.
• Driver: electric motor or diesel engine through a gearbox.
Certificate and datasheet:
• UL certificate
